Lab

Density Lab Introduction: meanness is a very(prenominal) most-valuable characteristic of all substances and it can be intent to draw any substance. To harness the parsimoniousness, first fate to dominate the heap of the substance, which is billd in grams. To find the caboodle sue the re-create air balance. Then find the volume of the substance by multiplying length * width* flower or if the substance is a liquid sue a graduated piston bedroom and mea positive(predicate) it reveal. Once you have all this information divide the trade/volume. Purpose: The purpose of the density lab is to find the density of both unfluctuating and irregular shaped objects and liquids. Materials: ·Triple channelize balance ·Graduated cylinder ·3 regular coat objects ·Ruler ·Aluminum cylinder ·Water · computer act: Part I: 1.To find the volume of a regular shaped object you need to measure the length, width, and height of apiece object. Use cm. 2.To calculate the volume use the formula V =L x W x H 3.To find the volume of the irregular shaped object you need to use water displacement for distributively object. Be sure to study the bottom of the meniscus. V of object = (V of water+Obj)-(v of water) 4. replicate for each of the 3 solid objects. 5.Calculate the density D= M/V Part II: 1.Find the host of a dry 10 mL graduated cylinder 2.Measure out exactly 10 ml of water 3.Mass the graduated cylinder with water 4.Calculate the mass of water 5.Find the density of water Part third: 1.Calculate the percent error of liquid A % Error= positive measure Experimental value x 100% actual Value Results: #17 L-10.5 cm Density- .843 g/cm W-1.3 cm M ass- 59.85 g H- 5.2 cm Vol.- 7.98 cm s! quared # 26 L- 6.9 cm Density- 1.38 g/cm W-2.5 cm Mass- 99.9 g H-4.2 cm Vol.- 72.4 cm squared #28 L- 8.1 cm Density- 1.27 g/cm W-...If you postulate to get a full essay, order it on our website: BestEssayCheap.com
